This exemption lets eligible aircraft ignore those specific weight limits.\n\n**Why this matters**\n\nThis lets agricultural operators carry heavier loads of chemicals or seeds, but only because they can instantly lighten the aircraft in an emergency by jettisoning the cargo.\n\n**Duration**\n\nThis exemption was time-limited and stopped having effect at the end of March 2013."}},"importantCases":[],"_links":{"self":"/api/acts/casa-ex38-11-exemption-maximum-take-off-weight-requirements-in-flight-manuals-or-other-documents-agr","history":"/api/acts/casa-ex38-11-exemption-maximum-take-off-weight-requirements-in-flight-manuals-or-other-documents-agr/history","analysis":"/api/acts/casa-ex38-11-exemption-maximum-take-off-weight-requirements-in-flight-manuals-or-other-documents-agr/analysis","conflicts":"/api/acts/casa-ex38-11-exemption-maximum-take-off-weight-requirements-in-flight-manuals-or-other-documents-agr/conflicts","importantCases":"/api/acts/casa-ex38-11-exemption-maximum-take-off-weight-requirements-in-flight-manuals-or-other-documents-agr/important-cases","documents":"/api/acts/casa-ex38-11-exemption-maximum-take-off-weight-requirements-in-flight-manuals-or-other-documents-agr/documents"}}
